c# - 使用 AutoMapper 时，此平台不支持 IDictionaryFactory

Question

我已通过 NuGet 将 AutoMapper 3.1.0-ci1027 安装到 MVC5 网站中。我用过 Owain Wraggs' Blog作为帮助我的向导。

我的配置文件是这样的:

public static class AutoMapperConfig
{
    public static void Initialize()
    {
        Mapper.Initialize(x =>
        {
            x.AddProfile<DomainToViewModelMappers>();
            x.AddProfile<ViewModelToDomainMappers>();
        });
    }
}

我正在从 Global.asax.cs.Application_Start() 中调用 Initialize() 方法:

AutoMapperConfig.Initialize();

但是，当我运行应用程序时，它在 Mapper.Initialize() 处崩溃。即使我不在其中包含任何代码，这也会发生。如果我注释掉这一行，代码运行良好，但当然，我不会使用 AutoMapper 来连接我的对象。

我看到的错误如下:

[PlatformNotSupportedException: This type is not supported on this platform IDictionaryFactory]
AutoMapper.Internal.PlatformAdapter.Resolve(Boolean throwIfNotFound) +320 AutoMapper.TypeMapFactory..cctor() +46

[TypeInitializationException: The type initializer for 'AutoMapper.TypeMapFactory' threw an exception.]

任何关于我遗漏的想法都将不胜感激。

这是 AutoMapper 中的一个错误，版本 3.1.0-ci1032 包含修复程序。结果证明支持可移植类库需要更多的工作:)
